This repository presents a MATLAB-based simulation of Bit Error Rate (BER) performance for BPSK and QPSK digital modulation schemes over an Additive White Gaussian ...

Abstract: In this paper, we propose the modified cycle-concentrating progressive-edge-growth (CC-PEG) algorithm for lifting protograph-based quasi-cyclic low-density parity-check (QC-LDPC) codes over ...

Abstract: Recently one decoding algorithm called as beyond belief propagation (BP) algorithm for LDPC Codes is derived using the knowledge of trapping set and different from standard BP algorithm, ...
